TYPICAL RESULTS
Obtaining meaningful results with the AVR-EB4-B-NXPB-SOD123W requires care,
experience, and an understanding of diode transient behavior and the impact of
inductive and capacitive parasitics. To assist the user, typical results are provided
below. The user should be able to reliably duplicate these results.
Additional test results are provided at the end of this manual, generated using the
actual shipped instrument and the specific jig(s) supplied with the instrument.
TYPICAL RESULTS:
CMMR1S-02
The Central Semi CMMR1S-02 is a 1A, 200V SOD123F fast-recovery rectifier. With the
amplitudes set to +107V and -83V, actual DUT current of +0.5A and -1A observed. The
full waveform (approximately 100 us wide) is shown below. The reverse transient
occurs 80 us after the start of the positive-going pulse.
10V/div / 25Ω = 400 mA/div. 20 us/div.
The SYNC pulse occurs shortly before the beginning of the reverse pulse. (The SYNC
pulse is used to trigger the oscilloscope, and the location of the rising edge of the
SYNC pulse is denoted by the orange “T” marker in the waveform above.) Changing the
time scale to zoom in on the 2 us wide reverse pulse gives:
